Lonesome Dove, Volume 2: Comanche Moon by Larry McMurtry

WHEN BUFFALO HUMP came into the big store in Austin, some of the warriors had found an old woman upstairs and had pulled her and had thrown her down the steps. Now they were dragging her through some white flour. They had killed the old man who owned the store with one of his own axes and had used the axe to chop open a couple of barrels of white flour. Some of the young warriors had never seen white flour and took delight in throwing it in the air and covering themselves with it. They also liked dragging the old woman through it while she shrieked. Two of the young warriors outraged her while Buffalo Hump picked out a few hatchets and put them in a sack. Then he came over and waited for the warrior who was outraging the old woman to finish. The woman's husband was lying dead only a few feet away, while, outside, his warriors were setting buildings afire and killing people as they tried to escape the flames. Some warriors rode their horses into white people's houses and looted everything they could carry. Six Texans were shot down in the street and scalped where they fell. The people of Austin ran like chickens and the Comanches pursued them like wolves, killing them as they ran with lances, or arrows, or tomahawks.

The raid had begun just at dawn but now the sun was well up. Buffalo Hump knew it was time to leave. The young men would have to throw away much of the loot they carried; they would not be able to carry it if there was a fast pursuit. They had killed four rangers in one little house but had seen no soldiers.
